STEAM COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 378,947, dated March 6,1888.

Application filed April .27, 1887.

To aZZ whom it may concern.-

Be it knownt'hat I, HENRY G. BALLARD, a citizen of the United States,residing at Red Oak, in the county of Montgomery and State of Iowa, haveinvented certain new and useful Improvements in Steam Cooking Apparatus;and I do declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification- Figure l of thedrawings is a front elevation of my improved steam-cooker. Fig. 2 is atop view with vessels D swung from over boiler. Fig. 3 is a sectionalview of valve-seat. Fig. 4 is a horizontal section showing the cut-01fand openingsf and f.

The invention is an improvement -in steam cookers and heaters; and itconsists in the construction and novel combination of parts, ashereinafter set forth.

Referring to the drawings, A designates a boiler provided with thevertical opposite pipes B O, which rise from its sides near the top, theformer being a steam-pipe and the latter a pipe for the return to theboiler of the water of condensation. The steam-pipe B has in its upperportion a diaphragm, I), provided with a seat, I), for the sphericalvalve b and the top of the said pipe above the valve is perforated, asat b, to allow escape of steam when the pressure becomes too great. Thetops of the pipes B and O are connected by the transverse pipe 0, asshown. The boiler A is provided with a proper inlet, a, for water, andabove its roof are the steamers or cooking-vessels D D. The boiler andvessels D are preferably cylindrical and are of equal diameter.

The vessels are of similar construction, and the top one is providedwith a lid or cover, cl. The said vessels are arranged one above anotherover the boiler, and are swung on the pipe B by the sleeves E, so thateach can be separately turnedlaterally from overthe boiler. The saidsleeves are held in position on the pipe B by the transverse clips 6 eon said pipe above and below each sleeve, and are connected to thecorresponding vessels by the steam-chambers F, whieh communicate withSerial No. 236,305. (No model.)

the pipe B through the openings f, and with the corresponding vesselthrough the opening f. lVhen any vessel D is turned laterally from overthe boiler by means of its handle G, its sleeve E turns over theadjacent opening f and automatically cuts off steam from said vessel.Each vessel is provided with a sliding door or cut-off, H, moving inways It, secured to its inner surface and adapted to cover the openingf, by which the corresponding steam-chamber F and vessel D communicate.

h is a knob attached to said door and passing through a horizontal slot,h in the side of the vessel. By means of said handle the door can heslid over the opening f without changing the position of the vessel, sothat the latter has both an automatic and non-automatic cutoff.

WVhen the vessels are vertically above the boiler, the pipe 0 acts as astop to the handle G, which abuts thereagainst.

Should the pressure of the steam become too great, it will lift thevalve Z) and escape through the perforated upper end of the steam-pipe,some portion going into the pipe 0, where it is condensed and returnedby the pipe 0 to the boiler.

By the described means any one of the vessels can be turned outward andautomatically cut off from the boiler without interfering with theoperation of the remaining vessels, or any one of the vessels may be cutoff by hand without changing its position.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination of the boiler, the vertical steam-pipe risingtherefrom, the steamvessels attached by sleeves to and turning onthesteam-pipe, the steamchambers connecting the vessels with thecorresponding sleeves and communicating with the steam-pipe through theopenings f and with the vessels through the openings f,and the slidingdoors H of the steam-vessels on one side of the correspondingsteam-chambers, the said slides moving on ways in the interior of thevessels and being provided with handles h, that move in slots in thesides of the vessel to close the opening f, substantially as specified.

' 2. The combination of the boiler, the steampipe rising therefrom andhaving its upper F, which communicate with the steam-pipe through theopenings f and with the corresponding steam-vessels through the openingsf, and the sliding doors H, moving in the ways h and provided with thehandles h, moving in the slots h, all constructed and arrangedsubstantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
